I've never had problems with the circuit until I moved it from a standard

Also, if I restart asterisk, all the b-channels come back. <br>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>You probably have noise on your T1 circuit, which is causing the PRI<br>
signalling to become corrupt. If this continues, expect that the T1
circuit<br>
will go down from time to time, for a few seconds each time. Your
solution is<br>
to call your telco and ask for a loopback test.<br>
